DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A stamping die for a rear suspension of an automobile comprises a base 1, a lower die 2 and an upper die 3. Support frames 18 are fixedly arranged at the four corners of the bottom wall of the lower die 2. The bottom wall of the support frame 18 is fixedly connected to the top wall of the base 1. Two sets of guide rods 7 are fixedly arranged on the rear side wall of the lower die 2. Two sets of guide sleeves 8 are fixedly arranged on the rear side wall of the upper die 3. The guide sleeves 8 are slidably connected to the guide rods 7. A die hole is arranged on the lower die 2. A movable die 10 is slidably arranged in the die hole. A convex die 14 is fixedly arranged at a position corresponding to the bottom wall of the upper die 3 and the die hole. The convex die 14 is adapted to the movable die 10. The movable die 10 is located on the bottom wall of the lower side of the lower die 2. The seat 17 is provided with a support assembly between the movable seat 17 and the base 1, the movable seat 17 and the side wall of the upper die 3 are provided with a driving assembly, and the top wall of the upper die 3 is installed with a downward pressing power structure, such as a hydraulic cylinder, to place the steel plate on the top wall of the lower die 2, and the upper die 3 moves downward, so that the punch 14 extends into the die hole and punches the steel plate. When the upper die 3 moves downward, the driving assembly drives the support assembly to move downward, so that the movable die 10 moves downward in the die hole, leaving space for stamping. After the stamping is completed, the upper die 3 moves upward, and the stamping assembly lifts the movable die 10 upward, so that the stamped automobile suspension product is ejected in the die hole. The structure is simple and easy to demould.

[0025] See also Figure 4The above-mentioned support components can be any one of them. The present application provides an embodiment, in which the support component includes a positioning platform 15, a moving platform 16 and a spring 12. A positioning platform 15 is fixedly arranged in the middle position of the top wall of the base 1, and a sliding hole is arranged on the top wall of the positioning platform 15. A moving platform 16 is slidingly arranged in the sliding hole. The top wall of the moving platform 16 is fixedly connected to the bottom wall of the moving seat 17. A spring 12 is fixedly arranged between the bottom wall of the moving seat 17 and the top wall of the base 1. The moving seat 17 slides in the sliding hole of the positioning platform 15 through the moving platform 16. When the moving mold 10 moves down in the mold hole, the moving platform 16 moves down in the sliding hole, and then the moving seat 17 contacts the top wall of the positioning platform 15. The moving position of the moving mold 10 is limited, so that the distance moved by the moving mold 10 in the mold hole is the depth of the stamping of the rear suspension of the automobile. After the stamping is completed, the spring 12 pushes the moving seat 17 upward, so that the moving mold 10 moves upward in the mold hole, so that the stamped suspension product can be ejected in the mold hole for easy demoulding.

[0026] See also Figure 4 Furthermore, multiple groups of springs 12 are provided and evenly distributed around the positioning platform 15. By providing multiple groups of springs 12, the force on the moving seat 17 can be more evenly applied, thereby improving the stability of the movement of the moving mold 10.

[0027] See also Figure 4 Furthermore, it also includes a limit block 19. The top wall of the movable seat 17 is located on the side of the movable die 10 and a plurality of limit blocks 19 are fixedly arranged. The top wall of the limit block 19 contacts the bottom wall of the lower die 2. When the spring 12 pushes the movable seat 17 upward, the top of the limit block 19 then contacts the bottom of the lower die 2. At this time, the top wall of the movable die 10 does not exceed the top end surface of the lower die 2, so that it is convenient to place the stamped steel plate.

[0028] See also Figure 1 and Figure 3 The above-mentioned driving assembly can be any one of them. The present application provides an embodiment, in which the driving assembly includes a connecting frame 13, a guide frame 6 and a top block 5.
